Claims. (ores-55.5)

This invention relates to a winding machine for yarn spools such as used in Axminster loomsand it is the general object of the invention to adapt the winding machine for use with spools having barrels of different diameters."

The spools used in Axminster looms have yarn wound thereon with the colors arranged according to the pattern desired. A number of spools all of the same kind are used in one loom and the spools all carry substantially the same length of yarn. A mill is likely to have spools of different barrel diameters, one group of spools be- Fig. 1 is a verticalsection through a winding machine'suc'h as shown-in my previously mentioned patent with my present invention applied thereto.

of Fig. 1, 1 Y I Fig. 4 is a plan view looking in'the direction of w arrow 4, Fig. 3,

ing of small diameter, another group of large diameter, while a third group may be of intermediate diameter. Since the start of the winding operation requires that'thewinding rolls have close driving contact with the spool barrel it is desirable that provision be made for locating the rolls in one setting when winding spools of one diameter, and locating them in other settings when spools of different diameters are'to be wound. It is accordingly an important object of my present invention to provide means 'for giving the rolls various relativezsettings at the start of the winding operation to permit the windingmachine to operate satisfactorily with spools of;

different diameters.

In my prior Patent No, 1,996,305 I have shown a winding machine wherein two rolls normally stationary during the winding operation cooperate with a third movable roll movable away from the other two rolls during the winding operation.

After the winding operation is completed the full spool will be removed and the movable roll returned to starting position by movement toward the normal position of the other rol-ls. It is a Fig. 5 is an enlarged rear elevation-of'the part of Fig. 1 showing the'stops, and

'6 is an enlarged horizontal section on line 6 6 of Fig.2. Referring to Fig. 1, 'my invention relates to a 5 winding machine having a frameifl on which a plurality of Winding rolls H, 12 and P3 are rotatably mounted. In the drawing Iv have shown only one side'of the machine, but it will further object of my present invention to-provide variable stop means to locate the movable roll at different distances from the stationary rolls so that spools of different barrel diameters may be employed.

In the previously mentioned patent I have shown a disk or the like which moves with the movable roll and it is a further object of my present invention to provide a manually operated mechanism having a plurality of stops for engagement with a part of the disk to cause the latter to stop the movable roll in different positions for the purposes already mentioned.

With these and other objects in view which will appear as the description proceeds, my invention residesin the combination and arrangement of parts hereinafter described and set forth.

In the accompanying drawing, wherein aconvenient embodiment of my invention is set forth,

be understood that much of the structure shown in Fig. 1 is duplicated'on the opposite end of the machine. The winding roll H is mounted in a bearing M- fixed to the machine frame-and 'ro-- tates always about a fixed axis. The roll i2 is the tension roll which is moved to the right" as viewed 'in Fig. 1 as the diameter of the spool increases. Roll 12 is continuously rotated-in a movable bearing I 5 on the upper-end of a three armedlever l6 loosely mounted-0n across shaft I"! supported by fixed bearings on thewinding machine frame.

The lower part of leven it is formed with 'asegmental-gear Z0 m'eshing'w ith apinion 2i fixed to across shaft 22 rotatable on the winding machine frame-about a fixed axis. A counterweight W is suspended from a chain 24 the upper end of whichis wrapped around a segmental winding pulley 25 keyed or otherwisesecuredto the shaft 22. A segmental ratchet Wheel26 is also fixed to shaft 22, and is normally engaged by one or more pawls 21 mounted upon pivot 28 fixed with respect to the machine frame. A release arm 13' swinging about axis 28 has pins 30' for engagement with the pawls 21'. During the winding operation weight W is raised and held elevated by the pawls 21.

The lever 161s also provided with a rearwardly extending arm 32 connected by a rod 33' to the piston 34; of a dash .pot .35 the purpose of which isto prevent t0'o rapid returnmovement of the parts to starting position when the pawls 2 are released. r

The upper roll [3 is mounted for rotation in an arm 48 pivoted on ashort shaft 42 on the frame. A-gear 4 4 is fixed to shaft 42 androtates in unison-With the arm 40. Gear 44' meshes with a" similar gear 45 fixed on the end of cross shaft II. An arm 46 is fixed to shaft II and supports a cylinder 41, which by reason of the gears 44 and 45, serves as a counter-weight for the top cylinder I3 when the latter is moved-from the full to the dotted line position shown in Fig. 1 to per mit removal of a full spool.

During the operation of the winding machine the upper roll I3 is held in fixed position by a latch 50 pivoted at 5| to the end of arm 40 on which the roll I3 rotates.

An upward extension plunger I9 mounted in a small cylinder 80 carried by the stand II. A spring 8| in cylinder 80 urges the spring plunger toward the periphery of the latch 50 is connected to a rod 52 which ex- The lower end of latch 50 engages'a holding V pawl 51 loosely mounted on a stud 58 fixed to A spring 59 holds the winding machine frame. the pawl 51 yieldingly in the position shown in Fig. 1 in holding relation with respect to the latch 50. A stop screw 60 on the latch 51 engages the bearing I4 to determine the left hand position of the upper end of pawl 51.

By means of mechanism not shown one or the other of the roll II or I3 will be driven positively, depending upon the direction in which the yarn Y is to be wound on the barrelB of the spool S.

In the operation of the mechanism thus far described the hold pawls 2'! will be released prior v to the start of the winding operation to permit the weight W to act through pinion 2I and rack to move the pressure or tension roll I2 to the left toward the rolls II and I3. During the winding operation the rolls II and I3 rotate about fixed axes and as yarn accumulates 0n the barrel B roll I2 moves to the right, thus rocking lever I6 to cause the segmental rack 26 and pinion 2I to raise the weight W. The hold pawls 21 operate to prevent retrograde movement of the ratchet wheel 26 and therefore hold the roll I2 against movement toward the stationary winding rolls. When the winding operation is completed rod 52 will be manipulated to release the top roll I3 so that it can be swung to the dotted position shown in Fig. 1. At this time the full spool is resting on roll II and against roll I2. The spool is then removed and hold pawls 21 raised by means of handle 29 to permit the tension roll I2 to move to the left toward roll I I. A new empty spool is then placed with its barrel in contact with the rolls I I and I2 and roll I3 is moved from the dotted to the full line position of Fig. 1 and latched in fixed position. The winding opera-' tion for the new spool is then started by mechanism not shown herein but fully set forth in my so that it may cooperate with spools having barrels of different diameters. In-carrying my in vention into effect I use one'of the cross beams I0 of the machine to support a stand 'II in which is rotatably mounted an inclined shaft "I2 having a hand wheel I3 at the upper end thereof. A disk I5 is secured to the'shaft I2 and is provided with-three notches 16, and I8, respectively,

each of which can cooperate with the spring of the disk I5 and into the notch'under it, and a stop pin 82 is provided to limit motion of the spring plunger under action of the spring.

Shaft I2 passes through a bearing 85 on stand II and has secured to its lower end a disk 86 carrying three spaced stop screws 91, 88 and 69, respectively. These stop screws are all located so they can move, one at a time, into the path of surface 90 on the segmental ratchet wheel 26. There is a notch in disk I5 for each stop screw and the plunger I9 holds the flange 86 with one or another of its stop screws in stopping position with respect to surface 90. As shown particularly in Fig. 4 the stop screws are of different lengths and extend different distances from the flange 86 and bearing 85 which limits motion to the left, Fig. l, of the flange, by engagement with its hub 92. 1

In the operation of my present invention, and assuming that a spool having a small barrel is to be wound, the hand wheel I3 will be turned to place the shortest of the stop screws in the path of surface 90. As the roll I2 moves to the left as already described it will be able to assume a position relatively close to the rolls II and I3 for the accommodation of a small barreled spool. If, on the other hand, the spool to be wound has a large barrel the longest of the stop screws will be placed in the path of surface 90 by appropriate turning of the hand wheel I3, and as the roll I2 approaches the rolls II and I3 it will be stopped at the proper distance to accommodate position for proper winding of the spool having an intermediate diameter.

While spools of but three different diameters have been mentioned, and for this reason only three stop screws have been shown in the flange 86, yet it is to be understood that the number of stop screws and their various lengths can be altered so that provision can be made for wind- .ing spools having a greater variation in diameter than the number set forth herein.

From the foregoing it, will be seen that I have provided simple means for adapting a winding machine for. use with spools having different barrel diameters. It is further seen that manual operation of :the hand wheel I3 serves to place one. or another of the stop screws in the path of surface 90 on the ratchet wheel 26 for the purpose of stopping the roll I2 in correct position as it moves toward the stationary rolls. It will further be seen that the spring plunger I9 will hold the selected stop screw in proper position without further attention by the attendant so that a series of spools all having the same'diameter may be wound by a single setting of the flange 86.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without de'- tioning mechanism to stop the third roll on the return stroke thereof toward said two rolls comprising an element movable alonga given path when said third roll has its return stroke, connections between saidelement and third roll to stop the latter on its return stroke when said element is stopped along said given pathfa fixed support, a plurality of stops carried by said support and movable one at a time into said given path at diiferent points therealong'and means to move any one of said stops into said path in stopping relation relatively to said element and move the other stops out of said path to cause said one stop to arrest motion of the element and stop the third roll on its return stroke toward said two rolls.
